Who makes 1 or a few transfers of 2 plus color design using plastisol transfers ? ... and what is the cost ?

1. for fewer colours, you can go for direct screen print using plastisol and fusing it well, rather than transfer if gradations arent used any.

2. Or else you may directly get fewer sheets printed on any deskjet/inkjet printer using transfer paper and get the work done yourself

3. I do not know any particular site, but a little search may be doing the needfull.
